Big campground near the dunes
Honeyman is a great campground. It is quite large with at least half a dozen loops of campsites. The sites include everything from basic campsite up to yurts.
There is a great playground near the center of camp and the nearby day use area has dune access for climbing and playing as well as a small lake.
Pre-pandemic it was possible to rent kayaks and paddleboats to use on the lake. I don't know if that has opened back up yet or not.
We have been many times and look forward to another trip there later this year.
